Buying Guide: Key Criteria for Choosing a DSL Modem Router

DSL Technology Compatibility

Not all DSL modem routers support the same technology. VDSL2 offers faster speeds than ADSL2+, but you need to check what your ISP uses. The Routers category page lists many options, but for DSL, look for devices that explicitly support VDSL2 with vectoring and G.INP for stable connections.

Most modern DSL routers also handle ADSL2+ as a fallback, which is helpful if you upgrade your plan later.

Wi-Fi Standards and Coverage

Today’s DSL routers often include dual-band Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax). Wi-Fi 6 offers better efficiency in crowded homes and faster speeds for multiple devices. If you game or stream in 4K, a router with Wi-Fi 6 is a smart investment. Our Best Modem Routers for Gaming article goes deeper into performance needs.

Wired Connectivity

Gigabit Ethernet ports are standard, but some models offer multi-gig ports (2.5 GbE) for future-proofing. Consider how many wired devices you have?consoles, PCs, smart TVs. More ports mean less reliance on Wi-Fi for latency-sensitive tasks.

Most DSL modem routers include four LAN ports, while pure modems may have only one. Choose based on your home setup.

ISP Compatibility and Setup

Always verify that the modem router is approved for your specific internet service provider. CenturyLink requires devices with VDSL2 support, while Cox and Spectrum use cable DOCSIS standards. The Best Modem Routers for Cox page offers a helpful comparison for cable users. For DSL, ensure the unit supports your ISP’s authentication method (PPPoE, IPoE, etc.) and any bonded line setups.

Final Thoughts

After reviewing the top contenders, two devices stand out for different needs. For a pure DSL modem that delivers rock-solid wired performance, the NETGEAR DSL (VDSL/ADSL) Modem (DM200-100NAS) is an excellent choice if you already own a separate router. If you prefer an all-in-one solution with Wi-Fi 6 and multi-gig speeds, the ARRIS Surfboard G34 DOCSIS 3.1 Cable Modem & Wi-Fi is a versatile option for cable internet users, though note it is not DSL compatible. For DSL households, the CenturyLink Technicolor C1100T or the C3000A provide reliable connectivity with built-in wireless. Consider your current ISP and future plans to make the best decision.

Frequently Asked Questions

Do I need a DSL modem router or separate devices?

A DSL modem router combo saves space and simplifies setup by combining the modem and router in one unit. Separate devices offer more flexibility for upgrades but require more cabling and configuration. For most home users, a combo is convenient and cost-effective.

Yes, many modem routers are compatible with CenturyLink, especially those supporting VDSL2 and ADSL2+. Models like the CenturyLink Technicolor C1100T and C3000A are designed for CenturyLink networks. Always check CenturyLink’s approved device list or consult our CenturyLink guide for recommendations.

What is the difference between VDSL and ADSL?

VDSL (Very High Bitrate Digital Subscriber Line) offers much faster download and upload speeds than ADSL (Asymmetric Digital Subscriber Line), especially over short distances. VDSL2 can reach up to 100 Mbps downstream, while ADSL2+ typically caps around 24 Mbps. If you have a fiber-fed DSL connection (FTTC), VDSL is common.

Is Wi-Fi 6 worth it for DSL internet?

Yes, even with DSL speeds, Wi-Fi 6 improves wireless efficiency and reduces congestion in homes with many devices. It also extends battery life for mobile devices. For future-proofing, investing in a DSL router with Wi-Fi 6 is a smart move. Read more about Wi-Fi standards on our blog.
